Exhibitionism: Exhibitionism is characterized by intense, sexually arousing fantasies, urges or behaviors involving exposure of the individual's genitals to an unsuspecting stranger. The individual with this problem, sometimes called a "flasher," feels a need to surprise, shock or impress his victims. The condition usually is limited to the exposure, with no other harmful advances made, although "indecent exposure" is illegal. Actual sexual contact with the victim is rare. However, the person may masturbate while exposing himself or while fantasizing about exposing himself.
